is this correct? This is partially correct. When the exposure is correct, there is no over-exposure. very slow shutter speeds won't blur everything unless you are handholding the camera at a very slow shutter speed. Put it on a tripod and anything that does not move (like a rock) should be sharp
If so I will need to learn more.
The GREY CARD seems a good idea,
What GREY CARD should I buy and how do I use it properly?
Most advice so far when I have searched the net seems to suggest
a GREY CARD rated at 18% ( some suggest 3 colour cards of WHITE, BLACK and GREY ).
